PCI Express (PCIe) Cache Data Protection

  • Overview
  • Resources


In the event of a system failure, subsystems with battery backed units (BBUs) require IT managers and technicians to respond quickly to recover the vital data upon a power fail condition – often within 24 to 72 hours – otherwise the data is lost and unrecoverable.

EXPRESSvault addresses these challenges with an architecture that ensures data in memory is immediately and reliably backed up without the use of expensive, inefficient UPS or battery technologies.

Simple to Use, Easy to Deploy and Cost Effective

The EXPRESSvault is a plug and play card that conveniently fits into a standard PCIe 3.0 x8 lane slot. The readily available PCIe slot on any off-the-shelf server or storage appliance eliminates the need for proprietary hardware and extra motherboard space. EXPRESSvault is provided with a Linux and or Windows driver compatible with standard PCIe peripheral command sets.

EXPRESSvault provides users many control and monitoring options to facilitate faster integration and verification, such as voltage monitoring, various backup and restore options, and interrupt support.
